Spotted spurge (Euphorbia maculata) is a common summer annual weed that thrives in lawns, gardens, and disturbed areas. Its low-growing, mat-forming habit and milky sap make it a persistent nuisance. The best herbicide for spotted spurge must effectively target both the foliage and root system to prevent regrowth and seed production.

This guide evaluates the most effective herbicides for controlling spotted spurge, focusing on their active ingredients, application methods, and suitability for different environments. Whether you are managing a lawn, garden, or landscape, this article will help you choose the right herbicide for spotted spurge control.
